Specification of Letters Patent.

Patented May 14, 1907.

Application filed September 2, 1904. Serial No. 223,899.

changed as required to correspond with the nameon the printing device or to conform to the requirements of a. card index system.

The invention is particularly adapted for stencil rinting devices in which a stencil is carried by a skeleton frame, and I have illustrat'ed this embodiment of the invention in I the accompanying drawings in which Figure 1 is a plan view of a stencil rioting device embody: the inventiom lg. 2 is an enlarged detdif top edge view of a portion of the stencil frame, the end of the frame hein shown in section. Fig. 3 is a longitudina sectional view of one corner of the stencil frame showing the tab in place. Fig. 4 is a sectional view on the line 4-4 of Fig. 1. Fig 5 is a bottom ed e view of the tab shown in Figs. 14. 1g. 6 is a sectional view corresponding to Fig. 3 and showing another form of tab. Fig. 7 is a bottom edge view of the tab shown in Fig. 5. Fig. 8

1s a top edge view of a portion of the stencil frame shown in Fig. 6. Fig. 9 shows another construction.

The frame 10 is open between its sides and ends, and provided at the edges of said o ening with channels 11 to receive the e ges of the stencil 12. In the construction illustrated in the drawings, the top or upper side 13 of the frame is formed by bending upon itself the materiel of which the frame is made to form the inwardly directed stencil channel 11, with the bent edge 14 forming the outer edge of the top of the frame.

In the construction shown in Figs. 1-5 the outer, edge of the frame, at any position between its ends, has two slots 15 and 16, one wall of the slot 16 being rovidod with a locking flange 17. This iange can be formed in cutting the slot, or by bending or pressing the edge of the slot inwardly after it is cut. The tab 18 has an elongated too 19 ands heel 20 arranged to enter the slots 15 and 16 respectively. The too 19 is formed by slitting the tab at .21 to receive the part 22 of the outer edge of the frame, and the heel is slitt-ed at 23 to receive the part 24 of the outer edge of the frame lying between the slots 15 and 16. In racticc, the toe of the tab is inserted in the s ot 15 alongside the stencil and moved forward until the heel can he carried down into the slot 16, thus bringing the tab into nrallol relation with the top of the frame. hen the tab is moved forward to its final position as shown in Fig. 1, the heel being carried est the flange 17 which iocks the tab in p ace. To facilitate inserting the toe and heel in the slots, I preferabiy cut them down to points 24 and 315 If desired, the heel or toe (or both the hes and too, as shown in Fig. 4) may be bent sidewise to frictionally engage the frame and tend to hold the tab in fixed position therein. To detach the tab 18 from the frame, the tab is moved backward (to the right in Fi 1) until the heel is carried past the loc lring flange, after which the heel is lifted out of the slot 16 and the too is pulled out of the Slot 15.

In the construction shown in Figs. 6 to 8, the frame is provided with a single slot 26 and the tab 27 is slitted lengthwise at 28 and 29 in its ends, one of said slits, as 28, being lon er than the other and forming a too 30 am a heel 31. In arranging this tab on the frame, the too is inserted in the slot 26 and moved forward until the heel can be pushed down into the slot, after which the tab is moved backward into the position shown in Fi 6. The toe and heel 30 and 31 are bent si cwisc to frictionally engage the frame and hold the tab in fixed position thereon, and it will be observed that the toe and heel project beyond the end walls of the slot to pre vent the tab from being detached from the frame accidentally. In detaching the tab 27 from the frame it is first; moved forward (to the left in Fi 6) and the heel is withdrawn from the s 0t, after which the too is pulled out of the slot.

sgstem may require.

In Fig. 9 the tab 32 is simply provided With a toe 33 formed by slitting the tab at 34. This toe which may be bent sidewise is inserted in the slot 35 in the frame and the tab is pushed down into the slot and then moved forward (to the left) until the end villall 36 of the slot is wedged tightly in the s it.

My resent invention is designed to simplify t e construction and decrease the cost of making printing devices of this character for use in a card index system. All frames, or a number of the frames, as desired, may be provided with the slots and the tabs can be arranged on ariy of the frames as the index This dispenses with e necessity of providing certain frames for use only as index frames. If all the frames are slotted, any one of them can be made an index frame at an time. If, forexample, the first stencil in t e A section of the system (which stencil would carr an indextab hearing index characters suc as A to B") became obsolete for any reason it would not be necessary to substitute for that stencil the stehcil in the second frame in the s stem, but itwould only be necessary to detac the index tab from the first frame and place it on the second frame. This is a very simple operation and avoids the necessity of removing the stencil from the second frame and insertin it in the first frame, which might result in in ury to the stencil. Furthermore, it will be readily understood that, with the present invention, the index tabs can be distributed throughout the frames in a tray and changed as often as desired and without necessitating a change of the stencils themselves. I may provide slots at several places in the frame so that all the tabs need not be arranged in alinemcnt in a tray. Index or other characters may be printed, stamped or otherwise affixed to the ta s.

VYithout limiting myself to the exact construction and arran ement of parts hcrcin shown and describer what I claim and desire to secure by Letters Patent is:

2. A stencil frame open between its sides and ends to ermit the stencil to be used for printing while in the frame and provided with a channel to receive the stencil and a slot, in its edge, in combination with a tab adapted to be inserted through said slot into said channel alongside the stencil, and means on the tab for h lding it in the slot.

3. A stencil frame open between its sides and ends to permit the stencil to be used for printing while in the frame and provided with two slots in its edge, in combination with a detachable tab having separate parts adapted to engage said slots.
